The brush head measures 3 inches in length and is filled with high-density wire designed to scrub out scale, soot, carbon deposits, and loose debris from the interior walls of 3\/4-inch tubing. A loop handle is included, available in either 1\/2-inch or 3\/4-inch configuration to suit operator preference or tool storage requirements. This is a hands-on service tool used by HVAC technicians, boiler mechanics, and plumbing professionals performing routine maintenance and tube preparation work.\u003c\/p\u003e\n\u003cp\u003eThe 1399 is suited for residential and light commercial boiler service, heat exchanger cleaning during annual tune-ups, and flue tube preparation before inspection or resealing. It is also appropriate for fan housings, burner ports, and nozzle passages where accumulated deposits restrict airflow or heat transfer. The 3-inch brush head length provides adequate contact area inside standard tube lengths without excessive resistance during insertion and withdrawal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch brush diameter sized for standard boiler and heat exchanger tube IDs\u003c\/li\u003e\n  \u003cli\u003e3-inch brush head length for thorough contact along tube walls\u003c\/li\u003e\n  \u003cli\u003eHigh-density wire fill removes scale, soot, and carbon buildup\u003c\/li\u003e\n  \u003cli\u003eLoop handle design available in 1\/2-inch or 3\/4-inch versions for storage compatibility\u003c\/li\u003e\n  \u003cli\u003eSuited for boiler, burner, nozzle, fan, and tube cleaning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for mechanical cleaning of 3\/4-inch internal diameter boiler tubes, flue tubes, heat exchanger passages, burner ports, nozzle openings, and fan housings where deposit removal is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShut down the boiler or heating system and allow all surfaces to cool completely before beginning any tube cleaning procedure. Ensure gas supply and electrical power are isolated per local IFGC and NEC requirements before accessing flue or burner components. Insert the brush with steady, even strokes to avoid bending the wire fill or damaging tube walls. Dispose of loosened scale and debris according to applicable environmental guidelines before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Head Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Loop handle (1\/2-inch or 3\/4-inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Boiler, burner, nozzle, fan, tube cleaning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Dimensions\u003c\/strong\u003e: 3 inches x 3 inches x 3 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILL-ROSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1399\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILL-ROSE","offers":[{"title":"Default Title","offer_id":51620049092914,"sku":"01399","price":20.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da5a71edd25f98d915e74f1ac5cd3e0c.jpg?v=1787339712","url":"https:\/\/voomisupply.com\/products\/mill-rose-1399-hc-tube-brush-boiler-tube-cleaning","provider":"Voomi Supply","version":"1.0","type":"link"}
